Peflnted June 2,1908.

Application filed September 13. 1905. Syrialll'oi aiazae.

Be it known that lyWnluriM 'HERMANN 801mm. a subject of the KingofiGreat Britain, residing in Montreal, Province of Quebec, Dominion ofCanada, mai1a 'er,'l1ave invented certain new'andiuseful l in rovementsin Linotype-Machineakof whicht 1e following is a pcciiication, referencebeing had to. the accompanying' drawings, forming a part hereof.

The "general object offthis invention is to simplify theconstruction"ofllinotype machines with a view toward reducing the number of parts required, avoiding the necessity,

where it is possible, of using such parts as are expensive tomanufacture or assemble and thereby eliecting a great saving in theconstruction vof these machines; and further-.

more, with a view toward making different members of the machine inoreconveniently separable and removable from the rest of the machine. I

. 'lhe resent improvements have to do particular y With the com osingmechanisl'n. The matrix releasing nec anism which forms apart of thecomposing mechanism-generally includes power supplynv devicesforactuating the same, the finger lreys'mere'ly serving 'to place themechanism under the control of the power supplying devices. Forlthispurpose it has been customary to employs continuously rotating-drum tocoo erate with cams corresponding with the di erent matrices, which camswere released by the keys so :is to come in contact Withthe drum and berotated thereby. iflhe provision of all of the cams required for thispurpose and of the continuously rotating: drum and power connectionstherefor not only renders the assembly of the maclnne expensive anddillicult 1n the first instance and these, aration and removal of thekeyboard an adjacent partsfrom time to time inconnenient, but increasesto a very great extent-the cost of construction.

The objection tooperating the matrix releasing mechanism direotlyfromthe key has not been due somuoh to a hard key action as to thedifiicultyof .ositively: releasing the matrices when the eys are operated ,veryquickly. By providing the cams and the continuouslyn era-tin .drum,itmattered not how qui y -he" eys were operated,

" since the regular and predetermined interval of time taken uindie-revolution of theoams a1waysinsure the positive release of theing'characters of a difierent matrices In accordance with the presentinvention, means arejpr'ovicled to overcome this objection to theoperation .of'the matrix.

. releasing mechanism directlyirom tl1e keys,-

and these meansfcomprise devices to arrest momentarily the action oftheescapenlents for-the matrices.

structioncf the matrix releasin mechanism isthereby greatly simplified.furthermore; new and improved escapen'ients-forthe mas trices arerovided and the connection {be}? I In this way the matrices re alwaysreleased properly While the con (TOMPANY, l1Il ITED, OF TORONTO. CANADA,A CORPORATION 01* tween the escapements and theescapement' rods are suchthat they can bere'adily sepa c rated at any time, as when it isdesiredtore' new the magazinefor the purposeofre lacs" ing it by anothercontainin matrices esp gace. Moreover. the escapement rods, key. rodsand their connections, guides and supports all. form, with thekey-board, a distinct compact and separable member which can be easilyand quickly removed from the rest of the machine.

The escapement pawls a are preferably made in one piece, as shown, beingsubstam' tially a semi-disk and havin ,-two="projec- 40 t ments haveconsisted of more than one part and the bottom plate of-the magazinehastions li and of, one on each side, which extend through the bottomplate a of the magazine toen'gage'the shoulders upon the matrices intheusual manner. These pawls are pivoted to oscillate in thebottom plate ofthe magazine and are actuated by the escapement rods 0 which have a freeconnection therewith. Heretofore, the escapegenerally included two ormore castings in 'order to furnish bearin forf-the esca ements; Theroyision' 'o such b 'earings as been absolute y necessaryf'inrsoineforms of 'escapements and, therefore, the; esca 'ement s' themselveshave not 'onl-ybeen d fficult and expensive to construct, but thehottion between each escapement rod and its 7 p corresponding escapementpawl is such that Ltheffulcrumsof the escapement rods, where- 130 tornplate of the magazine has had to be made in two or three parts and hasthus been an item "of considerable expense. In the present case by"'providin an escapement pawl with all parts integra it has not beennecessary to provide any bearings therefor other than its ownivot andconsequently the bottom plate the magazine does not have to beprovided-with bearinglpiec'es and may accordingly be constructe of sheetbrass thro'ughout its; entire 'length, suitable holes beingpunched-therein to permit theprojec'tions upon the-"escapements to" workthrough into the magazinal The connec-- a cjusted sidewise to theprecise extent, with "the magazine with the escapements secured theretomay be readily removed without first having to unfasten the connectionsbetween a tions comprises a PIOJGCiZlOIl and recess; the

--one on the rod and the other in the pawl, and

the direction in which the escapement pawls are removed when themagazine is taken off the machine is the direction inwhich theprojection extends. The escapement rods 0 are referably mounted tooscillate on a bar (1 which is secured to arms (1 pivoted upon bracketsd whichare fastened upon or integral with a frame piece D.

Extending across the top of and screwed to 'the' brackets 11 is aslotted guide (1 through which the escapement rods '0 may extend and, bymoving this guide d toward one siglepr the other, the screw holestherein being. elongated in order to permit this movement, thepositions'of the rods may be erenc'e td-the escapement awls; as isdesired, The lower ends of t ese rods 1 also preferably extend throughanother guide plated screwed u on the frame piece D in such away as to eadjustable 'SldQWiSG as the guide late (1 just described. Thebar dextends t rough slots. d in thebrackets d and clamps (1 are provided forthe arms d, whereby said arms may be movedltogether with the bar d tofurther ad'ustv the: position of the escapement rods wit respect to theescapement pawls. By means of these adjustments the variations in thelocation of v the escapement pawls upon different maga'-' zines can becompensated for and the roper alinement between the escapement ro s and1 9.5-

the pawlscan be maintained at all times. 1 The key rods 0 are mountedfor-vertical motion in suitable guides a and c andjtheir upper endspreferably extend through the guide plate d, as shown, They-f may. 'be10 adapted to impart an oscillating motion to the-esca ement rods 0 indifferent ways but referaby, as shown in Fig. '1, by means of inks c-and c. The links '0" are pivoted to brackets'c? secured upon a fixedpart such as the plate d. I The links 0 are pivoted in the lower :endsof the escapement rods. These links being normally at an angle to eachother (Fig; 1 )'-'}it is obvious that u on the reciprocating'movement ofa key r0 the oscillation of the corresponding escapement pawl will beeffected through this connection. Of course, there areotherways in whichthe connections between-the escapement rods and keyrods Inay bearranged. -For. purposes of illustrationand explanation, two'otherarrangements are presented'in this case. In

Fig; 5 the link connections between the'escapement rods andthe ke'y rodsare above momentarily the return movement of the es ca emjent pawls topermit the matrices to be as, in Fig. 1, they are below the fulcrums ofThe adjustment of In Fig. 6 the key rods are shown as directly connectedto the escape merit rods, while the adjusting mechanism is similar tothat shown in Fig. 5.

In" order to provide means for arresting re eased properly and in theproper'order p r-ices" is effected directly'from thekeys, a yieldingconnection'is provided between. each while at the same time the releaseof the matkey and the corre's onding key rod. In the present case'eacho' the key rods is provided the 'low er end, a spring 0 connecting the ilonger. arm otfiihis lever 'With'a point...higher up on the rod, whiletheshorter arm of "the lever with alever c which is pivoted thereon nearis arranged inthe path of the corresponding key, or may beotherwiseoperatively con-. 'nectedwith the end of the key.

Before the key. is depressed, the matrix releasing mechanism is m theposition shown in Fig. 1 and in the full lines of Fig. 7. Upon thedepression of the key, the mechanism is moved from the position showninfull lines in Fig. 7 to that shown in broken lines in said figure,thus releasing the forward matrix in the corresponding groove in themagazine,

.whichmatrix dro s down into its channel b from the mouth o themagazine. With the matrix. releasing mechanism now in'the position shownin full lines in Fig. 8, further depression of the key by the operator.will cause the movement of the lever a upon its pivot in the rod s andthe extension of the spring 0 will occur, while both the rods'c and c"and the escapement awl retaintl're same po-.

sition. As soon as t e operator releases the key, the spring immediatelycontracts to its normal length with the rods 0 and c and the escapementpawl still in their same positions. This, as will be obvious, will causea monie i a tary delay ordwell inthe return movement of the pawl afterthe operator has released the key, this movement being shown inFig. 9,

It is shown in thesefigures as secured to the machine by means of suitable'fastemngs, suchas two screws k, a ortion of the machine being into the pawis,

The magazine is preferably secured to the magazine delivery mouth B ofthe machine by such means as to permit it to be readily detached andremoved therefrom. For this urpos'e'the magazine and the magazinedeivery mouth may be provided with registering grooves in which aremovable key b may be: inserted to lockthe same together.

The magazineitself, as shown in Fig. 13, may we rovided with aprojection or flange or tl-c like indicated at a so that in placing themagazine. in position all that is necessary .to be: (one is to bring themagazine down upon the machine with the projection or flangek restingupon a fixed part such as a bar it, (indicatedin F ig. 13). As the projection or flange a is preferablyprovided near the upper end of themagazine, the latter may, When it has been placed upon the bar ls, beswung around upon t'hc same so that its forward end is brought down adjacent to the ma azine delivery mouth.

. It will be clearthat many changes in the construction of the mechanismshown and described may be made without departing from the spirit of theinvention and the im-- provements are not limited accordingly to theembodiment herein specifically referred to.

Having now particularly described and ascertained the nature of mysaidinvention and in what manner the same is to be performed, I declare'thatwhat'I claim is of the keys, the escapementaand'an operative connectionbetween each key'and the corresponding escapement consisting of twomembers and-means to preserve a fixed'relation between said membersuntil the matrix isreleased and to perinitr'elative movement betweensaid members after the matrix is released.
